BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a multilayered structure producingdecorative effects, and more particularly relates to a self-adherentwall decoration.

2. Description of Related Art

A conventional wall paper is used as wall decoration. For aestheticpurposes, the conventional wall paper is generally printed with colorsand/or patterns, and is generally cut into pieces of large sizes tocover a broad area of a wall in a room.

When in use, a backside of the conventional wall paper or the wall isfirstly coated with glue, wherein the glue is coated evenly on thebackside of the conventional wall paper or on the wall, and the gluehelps the conventional wall paper to adhere onto the wall. After thegluing and pasting, the conventional wall paper can provide an aestheticappearance in the room.

However, the conventional wall paper has the following shortcomings.

1. For a special decoration in a partial area of the wall, theconventional wall paper has to be cut into pieces of a smaller size.

2. The conventional wall paper fails to present a look of heavy texturesor to provide a creative layout of appearance under suitablearrangements, and thus lacks versatility of furnishing.

3. The glue is squeezed out from edges of the conventional wall papervery often when the conventional wall paper is pasted on the wall.

4. The conventional wall paper needs to be very light in weight in orderto be stuck onto the wall and can only be pasted on a smooth and flatwall.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide aself-adherent wall decoration that solves the difficulty in use due tosizes, incapability of presenting three-dimensional appearances andcreative layouts, spillover of glue of the conventional wall paper,limitation of light weight on the products, and limitation of the walltexture which can be applied.

The self-adherent wall decoration in accordance with the presentinvention comprises a body and two adhesive strips. The body is flexibleand has four sides, a wear layer, a vinyl print layer, a waterproof corelayer, and an underlayment layer. The four sides include two parallelsides that are equal to or longer than the rest of the four sides. Thewear layer is composed of poly(vinyl chloride), acrylate copolymer,dioctyl terephthalate, organotin thermal stabilizers, calcium carbonate,titanium dioxide, and pigment. The vinyl print layer is formed on a sideof the wear layer, and is composed of poly(vinyl chloride), acrylatecopolymer, dioctyl terephthalate, calcium carbonate, and pigment. Thewaterproof core layer is formed on a side of the vinyl print layer awayfrom the wear layer, and is composed of poly(vinyl chloride),acrylonitrile-butadiene-styrene copolymer, dioctyl terephthalate,calcium carbonate, antioxidants, and stearic acid salt. The underlaymentlayer is a poly(vinyl chloride) film, and is formed on a side of thewaterproof core layer away from the vinyl print layer. The two adhesivestrips are adhered to a side of the underlayment layer of the body awayfrom the waterproof core layer, wherein each one of the two adhesivestrips is located near a respective one of the two parallel sides.

Other objectives, advantages and novel features of the invention willbecome more apparent from the following detailed description when takenin conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1 to 4 , the self-adherent wall decorationcomprises a body 10 and two adhesive strips 20. The body 10 has foursides, a wear layer 11, a vinyl print layer 12, a waterproof core layer13, and an underlayment layer 14. Specifically, the self-adherent walldecoration is a wall panel.

The four sides of the body 10 include two parallel sides 101 that areequal to or longer than the rest of the four sides. The wear layer 11 iscomposed of 73 weight percent (wt %) of poly(vinyl chloride) andacrylate copolymer, 18 wt % of dioctyl terephthalate and organotinthermal stabilizers, 6 wt % of calcium carbonate, and 3 wt % of titaniumdioxide and pigment. The wear layer 11 provides a protective effect toprevent the self-adherent wall decoration from being easily scarred.Moreover, the wear layer 11 is transparent.

The vinyl print layer 12 is formed on a side of the wear layer 11, andis composed of 70 wt % of poly(vinyl chloride) and acrylate copolymer,20 wt % of dioctyl terephthalate, 5 wt % of calcium carbonate, and 5 wt% of pigment. In the present invention, with reference to FIGS. 1 and 3, the vinyl print layers 12 of different pieces of the self-adherentwall decoration have different growth ring patterns thereon, presentingwood-like textures.

The waterproof core layer 13 is formed on a side of the vinyl printlayer 12 away from the wear layer 11, and is composed of 22 wt % ofpoly(vinyl chloride), 10 wt % of acrylonitrile-butadiene-styrenecopolymer, 20 wt % of dioctyl terephthalate, 40 wt % of calciumcarbonate, and 8 wt % of antioxidants and stearic acid salt. Thewaterproof core layer 13 provides a waterproof effect for theself-adherent wall decoration. The underlayment layer 14 is a poly(vinylchloride) film, and is formed on a side of the waterproof core layer 13away from the vinyl print layer 12.

The two adhesive strips 20 are adhered to a side of the underlaymentlayer 14 of the body 10 away from the waterproof core layer 13, whereineach one of the two adhesive strips 20 is located near a respective oneof the two parallel sides 101 of the body 10. In such configurations, auser may spread the body 10, set the body 10 to a location on a wall,and press to paste the body 10 onto the wall through the two adhesivestrips 20. In this way, the user does not have to coat the body 10 withglue evenly, and spillover of glue would not happen. Each one of the twoadhesive strips 20 is a transparent pressure-sensitive tape, and has athickness between 0.3-3 millimeters (mm) Furthermore, the thickness ofeach adhesive strip 20 is preferred to be 0.5-1.5 mm.

The user may prepare multiple pieces of the self-adherent walldecoration, and paste them on the wall, so the multiple pieces of theself-adherent wall decoration may serve as the conventional wall paperthat fully cover the wall. Because the two adhesive strips 20 havefluidity, adhesive composition of the adhesive strip 20 can permeateinto an uneven textured surface of the wall, and the self-adherent walldecoration is thereby firmly stuck onto the wall.

Moreover, with reference to FIG. 5 , due to the compositions of the wearlayer 11, the vinyl print layer 12, the waterproof core layer 13, andthe underlayment layer 14, the body 10 is flexible, and can be wellpasted on a curved wall 50.

With reference to FIGS. 6 to 8 , the user may arrange several pieces ofthe self-adherent wall decoration into a special pattern, and paste themon a small area of the wall 60. Since the several pieces of theself-adherent wall do not fully cover the wall 60, they may provide athree-dimensional appearance with heavy textures and weight.

With the aforementioned technical features, the self-adherent walldecoration of the present invention has the following advantages.

1. The usage amount of the pieces of the self-adherent wall decorationis decided by the user, so the user may design how to paste and how manyof the pieces of the self-adherent wall decoration to be pasted onto thewall 50, 60.

2. Since each piece of the self-adherent wall decoration comprisesmultiple layers, i.e. the wear layer 11, the vinyl print layer 12, thewaterproof core layer 13, and the underlayment layer 14, theself-adherent wall decoration has a thickness. Hence a single piece or afew pieces of the self-adherent wall decoration will provide athree-dimensional appearance, and may provide a look of heavy texturesas a special aesthetic improvement.

3. Spillover of glue is absolutely avoided.

4. The intrinsic characteristics of the two adhesive strips 20 make thetwo adhesive strips 20 able to fit on the textured surface of the wall,for example, an orange peel wall. The two adhesive strips 20 can bepasted firmly on walls of different material, e.g., a granite wall, aquartz wall, a plastic wall, a stucco wall, a drywall, etc. Hence,compared to the conventional products, the self-adherent wall decorationhas convenience for operation, good viscosity, and can be pasted on theuneven wall firmly.
